FIELD OF THE INVENTION

The present invention relates to heterocyclic amides that are useful as modulators of transmembrane protein 173 (TMEM173), which is also known as STING (Stimulator of Interferon Genes)) and methods of making and using the same.

BACKGROUND OF THE INVENTION

Vertebrates are constantly threatened by the invasion of microorganisms and have evolved mechanisms of immune defense to eliminate infective pathogens. In mammals, this immune system comprises two branches; innate immunity and adaptive immunity. The innate immune system is the first line of defense which is initiated by Pattern Recognition Receptors (PRRs) which detect ligands from the pathogens as well as damage associated molecular patterns (Takeuchi O. et al, Cell, 2010: 140, 805-820). A growing number of these receptors have been identified including Toll-like receptors (TLRs), C-type lectin receptors, retinoic acid inducible gene I (RIG-I)-like receptors and NOD-like receptors (NLRs) and also double stranded DNA sensors. Activation of PRRs leads to up-regulation of genes involved in the inflammatory response including type 1 interferons, pro-inflammatory cytokines and chemokines which suppress pathogen replication and facilitate adaptive immunity.

The adaptor protein STING (Stimulator of Interferon Genes), also known as TMEM 173, MPYS, MITA and ERIS, has been identified as a central signaling molecule in the innate immune response to cytosolic nucleic acids (Ishikawa H and Barber G N, Nature, 2008: 455, 674-678; WO2013/1666000). Activation of STING results in up-regulation of IRF3 and NFκB pathways leading to induction of Interferon-β and other cytokines. STING is critical for responses to cytosolic DNA of pathogen or host origin, and of unusual nucleic acids called Cyclic Dinucleotides (CDNs)

CDNs were first identified as bacterial secondary messengers responsible for controlling numerous responses in the prokaryotic cell. Bacterial CDNs, such as c-di-GMP are symmetrical molecules characterized by two 3′,5′ phosphodiester linkages.

Direct activation of STING by bacterial CDNs has recently been confirmed through X-ray crystallography (Burdette D L and Vance R E, Nature Immunology, 2013: 14, 19-26). Bacterial CDNs and their analogues have consequently attracted interest as potential vaccine adjuvants (Libanova R. et al, Microbial Biotechnology 2012: 5, 168-176; WO2007/054279, WO2005/087238).

More recently, the response to cytosolic DNA has been elucidated and shown to involve generation, by an enzyme called cyclic GMP-AMP synthase (cGAS, previously known as C6orf150 or MB21D1), of a novel mammalian CDN signaling molecule identified as cGAMP, which then activates STING. Unlike bacterial CDNs, cGAMP is an unsymmetrical molecule characterized by its mixed 2′,5′ and 3′,5′ phosphodiester linkages. (Gao P et al, Cell, 2013: 153, 1094-1107). Interaction of cGAMP (II) with STING has also been demonstrated by X-ray crystallography (Cai X et al, Molecular Cell, 2014: 54, 289-296).

Interferon was first described as a substance which could protect cells from viral infection (Isaacs & Lindemann, J. Virus Interference. Proc. R. Soc. Lon. Ser. B. Biol. Sci 1957: 147, 258-267). In man, the type I interferons are a family of related proteins encoded by genes on chromosome 9 and encoding at least 13 isoforms of interferon alpha (IFNα) and one isoform of interferon beta (IFNβ). Recombinant IFNα was the first approved biological therapeutic and has become an important therapy in viral infections and in cancer. As well as direct antiviral activity on cells, interferons are known to be potent modulators of the immune response, acting on cells of the immune system.

Administration of a small molecule compound which could modulate the innate immune response, including the activation or inhibition of type I interferon production and other cytokines, could become an important strategy for the treatment or prevention of human diseases including viral infections and autoimmune disease. This type of immunomodulatory strategy has the potential to identify compounds which may be useful not only in infectious diseases innate immunity but also in cancer (Zitvoge, L., et al., Nature Reviews Immunology, 2015 15(7), p 405-414), allergic diseases (Moisan J. et al, Am. J. Physiol. Lung Cell Mol. Physiol., 2006: 290, L987-995), neurodegenerative diseases such as amyotrophic lateral sclerosis and multiple sclerosis (Lemos, H. et al., J. Immunol, 2014: 192(12), 5571-8; Cirulli, E. et al., Science, 2015: 347(6229), 1436-41; Freischmidt, A., et al., Nat. Neurosci., 18(5), 631-6), other inflammatory conditions such as irritable bowel disease (Rakoff-Nahoum S., Cell., 2004, 23, 118(2): 229-41), and as vaccine adjuvants (Persing et al. Trends Microbiol 2002: 10(10 Suppl), S32-7 and Dubensky et al., Therapeutic Advances in Vaccines, published on line Sep. 5, 2013).

STING is essential for antimicrobial host defense, including protection against a range of DNA and RNA viruses and bacteria (reviewed in Barber et al. Nat. Rev. Immunol. 2015: 15(2): 87-103, Ma and Damania, Cell Host & Microbe, 2016: 19(2) 150-158). Herpesviridae, Flaviviridae, Coronaviridae, Papillomaviridae, Adenoviridae, Hepadnaviridae, ortho- and paramyxoviridae and rhabdoviridae have evolved mechanisms to inhibit STING mediated Type I interferon production and evade host immune control (Holm et al, Nat Comm. 2016: 7:10680; Ma et al, PNAS 2015: 112(31) E4306-E4315; Wu et al, Cell Host Microbe 2015: 18(3) 333-44; Liu et al, J Virol 2016. 90(20) 9406-19; Chen et al., Protein Cell 2014: 5(5) 369-B1; Lau et al, Science 2013: 350(6260) 568-71; Ding et al, J Hepatol 2013: 59(1) 52-8; Nitta et al, Hepatology 2013 57(1) 46-58; Sun et al, PloS One 2012: 7(2) e30802; Aguirre et al, PoS Pathog 2012: 8(10) e1002934; Ishikawa et al, Nature 2009: 461(7265) 788-92). Thus, small molecule activation of STING could be beneficial for treatment of these infectious diseases.

In contrast, increased and prolonged type I IFN production is associated with a variety of chronic infections, including Mycobacteria (Collins et al, Cell Host Microbe 2015: 17(6) 820-8); Wassermann et al., Cell Host Microbe 2015: 17(6) 799-810; Watson et al., Cell Host Microbe 2015: 17(6) 811-9), Franciscella (Storek et al., J Immunol. 2015: 194(7) 3236-45; Jin et al., J Immunol. 2011: 187(5) 2595-601), Chlamydia (Prantner et al., J Immunol 2010: 184(5) 2551-60; Plasmodium (Sharma et al., Immunity 2011: 35(2) 194-207 and HIV (Herzner et al., Nat Immunol 2015 16(10) 1025-33; Gao et al., Science 2013: 341(6148) 903-6. Similarly, excess type I interferon production is found among patients with complex forms of autoimmune disease. Genetic evidence in humans and support from studies in animal models support the hypothesis that inhibition of STING results in reduced type I interferon that drives autoimmune disease (Crow Y J, et al., Nat. Genet. 2006; 38(8) 38917-920, Stetson D B, et al., Cell 2008; 134587-598). Therefore, inhibitors of STING provide a treatment to patients with chronic type I interferon and proinflammatory cytokine production associated with infections or complex autoimmune diseases. Allergic diseases are associated with a Th2-biased immune-response to allergens. Th2 responses are associated with raised levels of IgE, which, via its effects on mast cells, promotes a hypersensitivity to allergens, resulting in the symptoms seen, for example, in allergic rhinitis and asthma. In healthy individuals the immune-response to allergens is more balanced with a mixed Th2/Th1 and regulatory T cell response. Induction of Type 1 interferons have been shown to result in reduction of Th2-type cytokines in the local environment and promote Th1/Treg responses. In this context, induction of type 1 interferons by, for example, activation of STING, may offer benefit in treatment of allergic diseases such as asthma and allergic rhinitis (Huber J. P. et al J Immunol 2010: 185, 813-817).

Compounds that bind to STING and act as agonist have been shown to induce type 1 interferons and other cytokines on incubation with human PBMCs. Compounds which induce human interferons may be useful in the treatment of various disorders, for example the treatment of allergic diseases and other inflammatory conditions for example allergic rhinitis and asthma, the treatment of infectious diseases, neurodegenerative disease, pre-cancerous syndromes and cancer, and may also be useful as immugenic composition or vaccine adjuvants. Compounds that bind to STING may act as antagonists and could be useful in the treatment, for example of autoimmune diseases. It is envisaged that targeting STING with activation or inhibiting agents may be a promising approach for treating diseases and conditions in which modulation for the type 1 IFN pathway is beneficial, including inflammatory, allergic and autoimmune diseases, infectious diseases, cancer, pre-cancerous syndromes and as immugenic composition or vaccine adjuvants.

Skin cancers and various skin viral infections involve immune privileged environment and activation of local immune response to the lesions may be a topical therapeutic approach. STING agonists may be used for treating viral warts, superficial skin cancers and premalignant actinic keratoses. By a dual mechanism of action, STING activation (e.g., via microneedle patch delivery or topical formulation) may be used to control HPV directly via antiviral type I interferon production and indirectly by enhancing the adaptive immune response downstream of innate immune activation. STING agonist can activate the innate immune response in the lesion and drive the anti-HPV T-cell response.

Recent evidence has indicated that spontaneous activation of the STING pathway within tumor-resident dendritic cells leads to type I IFN production and adaptive immune responses against tumors. Furthermore, activation of this pathway in antigen presenting cells (APCs) within the tumor microenvironment drives the subsequent T-cell priming against tumor-associated antigens.

The compounds of this invention modulate the activity of STING, and accordingly, may provide a beneficial therapeutic impact in treatment of diseases, disorders and/or conditions in which modulation of STING (Stimulator of Interferon Genes) is beneficial, for example for inflammation, allergic and autoimmune diseases, infectious diseases, cancer, pre-cancerous syndromes and as vaccine adjuvants.

The length of the linking groups defined herein represents the lowest number of atoms in a direct chain composed of —R^(A1)-A-R^(A2)— and/or —R^(B1)—B—R^(B2)— and/or —R^(C1)—C—R^(C2)—. For example, when B is an optionally substituted phenyl, the linking group —R^(B1)—B—R^(B2)— may be represented as —(CH₂)-phenyl-(CH₂)—. This linking group is characterized as a 4-membered linking group when the 2 —(CH₂)— moieties are located on adjacent carbon atoms of the phenyl ring (1,2 substituted phenyl). In another embodiment, this linking group is characterized as a 6-membered linking group when the 2 —(CH₂)— moieties are substituted at para positions on the phenyl ring (1,4 substituted phenyl). It will be understood that any alkyl, alkenyl, or alkynyl group or moiety of A, B or C is a straight or branched-alkyl, alkenyl, or alkynyl group or moiety. For example, a —R^(B1)—B—R^(B2)— linking group, wherein B is —C₁-C₁₀alkyl- may contain an 8-membered linking group having a (C₁-C₄alkyl) branching group or 2-4 (C₁-C₃alkyl) branching groups, for example, 4 branching methyl groups (2 gem-dimethyl groups) or 2 branching methyl groups.

The compounds of this invention may contain one or more asymmetric centers (also referred to as a chiral center), such as a chiral carbon, or a chiral —SO— moiety. Compounds of this invention containing one or more chiral centers may be present as racemic mixtures, diastereomeric mixtures, enantiomerically enriched mixtures, diastereomerically enriched mixtures, or as enantiomerically or diastereomerically pure individual stereoisomers.

The stereochemistry of the chiral center present in compounds of this invention is generally represented in the compound names and/or in the chemical structures illustrated herein. Where the stereochemistry of a chiral center present in a compound of this invention, or in any chemical structure illustrated herein, is not specified, the structure is intended to encompass any stereoisomer and all mixtures thereof. Accordingly, the present invention encompasses all isomers of the compounds of Formula (I-N), (I-P) or (I), and salts thereof, whether as individual isomers isolated such as to be substantially free of the other isomer (i.e. pure) or as mixtures (i.e. racemates and racemic mixtures). An individual isomer isolated such as to be substantially free of the other isomer (i.e. pure) may be isolated such that less than 10%, particularly less than about 1%, for example less than about 0.1% of the other isomer is present.

Individual stereoisomers of a compound of this invention may be resolved (or mixtures of stereoisomers may be enriched) using methods known to those skilled in the art. For example, such resolution may be carried out (1) by formation of diastereoisomeric salts, complexes or other derivatives; (2) by selective reaction with a stereoisomer-specific reagent, for example by enzymatic oxidation or reduction; or (3) by gas-liquid or liquid chromatography in a chiral environment, for example, on a chiral support such as silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where the desired stereoisomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired form. Alternatively, specific stereoisomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer to the other by asymmetric transformation.

The invention also includes various deuterated forms of the compounds of this invention. Each available hydrogen atom attached to a carbon atom may be independently replaced with a deuterium atom. A person of ordinary skill in the art will know how to synthesize deuterated forms of the compounds of this invention. For example, α-deuterated α-amino acids are commercially available or may be prepared by conventional techniques (see for example: Elemes, Y. and Ragnarsson, U. J. Chem. Soc., Perkin Trans. 1, 1996, 6, 537-40). Employing such compounds may allow for the preparation of compounds in which the hydrogen atom at a chiral center is replaced with a deuterium atom. Other commercially available deuterated starting materials may be employed in the preparation of deuterated analogs of the compounds of this invention (see for example: methyl-d₃-amine available from Aldrich Chemical Co., Milwaukee, Wis.), or they may be synthesized using conventional techniques employing deuterated reagents (e.g. by reduction using lithium aluminum deuteride or sodium borodeuteride or by metal-halogen exchange followed by quenching with D₂O or methanol-d₃).

Suitable pharmaceutically acceptable salts of the compounds of Formula (I-N), (I-P) or (I) can include acid addition salts or base addition salts. For reviews of suitable pharmaceutically acceptable salts see Berge et al., J. Pharm. Sci., 66:1-19, (1977) and P. H. Stahl and C. G. Wermuth, Eds., Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim/Zürich:Wiley-VCH/VHCA (2002).

Salts of the compounds of Formula (I-N), (I-P) or (I) containing a basic amine or other basic functional group may be prepared by any suitable method known in the art, such as treatment of the free base with a suitable inorganic or organic acid. Examples of pharmaceutically acceptable salts so formed include acetate, adipate, ascorbate, aspartate, benzenesulfonate, benzoate, camphorate, camphor-sulfonate (camsylate), caprate (decanoate), caproate (hexanoate), caprylate (octanoate), carbonate, bicarbonate, cinnamate, citrate, cyclamate, dodecylsulfate (estolate), ethane-1,2-disulfonate (edisylate), ethanesulfonate (esylate), formate, fumarate (hemi-fumarate, etc.), galactarate (mucate), gentisate (2,5-dihydroxybenzoate), glucoheptonate (gluceptate), gluconate, glucuronate, glutamate, glutarate, glycerophosphorate, glycolate, hippurate, hydrobromide, hydrochloride (dihydrochloride, etc.), hydroiodide, isobutyrate, lactate, lactobionate, laurate, maleate, malate, malonate, mandelate, methanesulfonate (mesylate), naphthalene-1,5-disulfonate (napadisylate), naphthalene-sulfonate (napsylate), nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, phosphate (diphosphate, etc.), proprionate, pyroglutamate, salicylate, sebacate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate (tosylate), undecylenate, 1-hydroxy-2-naphthoate, 2,2-dichloroacetate, 2-hydroxyethanesulfonate (isethionate), 2-oxoglutarate, 4-acetamidobenzoate, and 4-aminosalicylate.

Salts of the disclosed compounds containing a carboxylic acid or other acidic functional group can be prepared by reacting with a suitable base. Such a pharmaceutically acceptable salt may be made with a base which affords a pharmaceutically acceptable cation, which includes alkali metal salts (especially sodium and potassium), alkaline earth metal salts (especially calcium and magnesium), aluminum salts and ammonium salts, as well as salts made from physiologically acceptable organic bases such as trimethylamine, triethylamine, morpholine, pyridine, piperidine, picoline, dicyclohexylamine, N,N-dibenzylethylenediamine, 2-hydroxyethylamine, bis-(2-hydroxyethyl)amine, tri-(2-hydroxyethyl)amine, procaine, dibenzylpiperidine, dehydroabietylamine, N,N-bisdehydroabietylamine, glucamine, N-methylglucamine, collidine, choline, quinine, quinoline, and basic amino acids such as lysine and arginine.

The invention includes within its scope all possible stoichiometric and non-stoichiometric forms of the salts (e.g., hydrobromide, dihydrobromide, fumarte, hemi-fumarate, etc) of the compounds of Formula (I-N), (I-P) or (I).

When a disclosed compound or its salt is named or depicted by structure, it is to be understood that the compound or salt, including solvates (particularly, hydrates) thereof, may exist in crystalline forms, non-crystalline forms or a mixture thereof. The compound or salt, or solvates (particularly, hydrates) thereof, may also exhibit polymorphism (i.e. the capacity to occur in different crystalline forms). These different crystalline forms are typically known as “polymorphs.” It is to be understood that the invention includes all polymorphs of any compound of this invention, e.g., all polymorphic forms of any compound named or depicted by structure herein, including any salts and/or solvates (particularly, hydrates) thereof.

Polymorphs have the same chemical composition but differ in packing, geometrical arrangement, and other descriptive properties of the crystalline solid state. Polymorphs, therefore, may have different physical properties such as shape, density, hardness, deformability, stability, and dissolution properties. Polymorphs typically exhibit different melting points, IR spectra, and X-ray powder diffraction patterns, which may be used for identification. It will be appreciated that different polymorphs may be produced, for example, by changing or adjusting the conditions used in crystallizing/recrystallizing the compound. Polymorphic forms may be characterized and differentiated using a number of conventional analytical techniques, including, but not limited to, X-ray powder diffraction (XRPD) patterns, infrared (IR) spectra, Raman spectra, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and solid state nuclear magnetic resonance (SSNMR).

The skilled artisan will appreciate that pharmaceutically acceptable solvates (particularly, hydrates) of a compound of Formula (I-N), (I-P) or (I), including pharmaceutically acceptable solvates of a pharmaceutically acceptable salt of a compound of Formula (I-N), (I-P) or (I), may be formed when solvent molecules are incorporated into the crystalline lattice during crystallization. Solvates may involve non-aqueous solvents such as ethanol, or they may involve water as the solvent that is incorporated into the crystalline lattice. Solvates wherein water is the solvent that is incorporated into the crystalline lattice are typically referred to as “hydrates.”

The present invention includes within its scope all possible stoichiometric and non-stoichiometric salt and/or hydrate forms.

Salts and solvates (e.g. hydrates and hydrates of salts) of the compounds of the invention which are suitable for use in medicine are those wherein the counterion or associated solvent is pharmaceutically acceptable. Salts having non-pharmaceutically acceptable counterions are within the scope of the present invention, for example, for use as intermediates in the preparation of other compounds of the invention.

Typically, a pharmaceutically acceptable salt may be readily prepared by using a desired acid or base as appropriate. The resultant salt may crystallize or precipitate from solution, or form by trituration, and may be recovered by filtration, or by evaporation of the solvent.

Because the compounds of this invention are intended for use in pharmaceutical compositions it will readily be understood that they are each preferably provided in substantially pure form, for example at least 60% pure, more suitably at least 75% pure and preferably at least 85%, especially at least 98% pure (% are on a weight for weight basis). Impure preparations of the compounds may be used for preparing the more pure forms used in the pharmaceutical compositions.

The invention encompasses all prodrugs of the compounds of this invention, which upon administration to the recipient are capable of providing (directly or indirectly) a compound of this invention, or an active metabolite or residue thereof. Such derivatives are recognisable to those skilled in the art, without undue experimentation. Nevertheless, reference is made to the teaching of Burger's Medicinal Chemistry and Drug Discovery, 5^(th) Edition, Vol 1: Principles and Practice, which is incorporated herein by reference to the extent of teaching such derivatives.

It is to be further understood that the present invention includes within its scope all tautomeric or isomer forms of any free base form of the compounds of this invention as well as all possible stoichiometric and non-stoichiometric salt forms.

As used herein, the terms “cancer,” “neoplasm,” and “tumor” are used interchangeably and, in either the singular or plural form, refer to cells that have undergone a malignant transformation that makes them pathological to the host organism. Primary cancer cells can be readily distinguished from non-cancerous cells by well-established techniques, particularly histological examination. The definition of a cancer cell, as used herein, includes not only a primary cancer cell, but any cell derived from a cancer cell ancestor. This includes metastasized cancer cells, and in vitro cultures and cell lines derived from cancer cells. When referring to a type of cancer that normally manifests as a solid tumor, a “clinically detectable” tumor is one that is detectable on the basis of tumor mass; e.g., by procedures such as computed tomography (CT) scan, magnetic resonance imaging (MRI), X-ray, ultrasound or palpation on physical examination, and/or which is detectable because of the expression of one or more cancer-specific antigens in a sample obtainable from a patient. Tumors may be a hematopoietic (or hematologic or hematological or blood-related) cancer, for example, cancers derived from blood cells or immune cells, which may be referred to as “liquid tumors.” Specific examples of clinical conditions based on hematologic tumors include leukemias such as chronic myelocytic leukemia, acute myelocytic leukemia, chronic lymphocytic leukemia and acute lymphocytic leukemia; plasma cell malignancies such as multiple myeloma, MGUS and Waldenstrom's macroglobulinemia; lymphomas such as non-Hodgkin's lymphoma, Hodgkin's lymphoma; and the like.

The cancer may be any cancer in which an abnormal number of blast cells or unwanted cell proliferation is present or that is diagnosed as a hematological cancer, including both lymphoid and myeloid malignancies. Myeloid malignancies include, but are not limited to, acute myeloid (or myelocytic or myelogenous or myeloblastic) leukemia (undifferentiated or differentiated), acute promyeloid (or promyelocytic or promyelogenous or promyeloblastic) leukemia, acute myelomonocytic (or myelomonoblastic) leukemia, acute monocytic (or monoblastic) leukemia, erythroleukemia and megakaryocytic (or megakaryoblastic) leukemia.

These leukemias may be referred together as acute myeloid (or myelocytic or myelogenous) leukemia (AML). Myeloid malignancies also include myeloproliferative disorders (MPD) which include, but are not limited to, chronic myelogenous (or myeloid) leukemia (CML), chronic myelomonocytic leukemia (CMML), essential thrombocythemia (or thrombocytosis), and polcythemia vera (PCV). Myeloid malignancies also include myelodysplasia (or myelodysplastic syndrome or MDS), which may be referred to as refractory anemia (RA), refractory anemia with excess blasts (RAEB), and refractory anemia with excess blasts in transformation (RAEBT); as well as myelofibrosis (MFS) with or without agnogenic myeloid metaplasia.

Hematopoietic cancers also include lymphoid malignancies, which may affect the lymph nodes, spleens, bone marrow, peripheral blood, and/or extranodal sites. Lymphoid cancers include B-cell malignancies, which include, but are not limited to, B-cell non-Hodgkin's lymphomas (B-NHLs). B-NHLs may be indolent (or low-grade), intermediate-grade (or aggressive) or high-grade (very aggressive). Indolent Bcell lymphomas include follicular lymphoma (FL); small lymphocytic lymphoma (SLL); marginal zone lymphoma (MZL) including nodal MZL, extranodal MZL, splenic MZL and splenic MZL with villous lymphocytes; lymphoplasmacytic lymphoma (LPL); and mucosa-associated-lymphoid tissue (MALT or extranodal marginal zone) lymphoma. Intermediate-grade B-NHLs include mantle cell lymphoma (MCL) with or without leukemic involvement, diffuse large cell lymphoma (DLBCL), follicular large cell (or grade 3 or grade 3B) lymphoma, and primary mediastinal lymphoma (PML). High-grade B-NHLs include Burkitt's lymphoma (BL), Burkitt-like lymphoma, small non-cleaved cell lymphoma (SNCCL) and lymphoblastic lymphoma. Other B-NHLs include immunoblastic lymphoma (or immunocytoma), primary effusion lymphoma, HIV associated (or AIDS related) lymphomas, and post-transplant lymphoproliferative disorder (PTLD) or lymphoma. B-cell malignancies also include, but are not limited to, chronic lymphocytic leukemia (CLL), prolymphocytic leukemia (PLL), Waldenstrom's macroglobulinemia (WM), hairy cell leukemia (HCL), large granular lymphocyte (LGL) leukemia, acute lymphoid (or lymphocytic or lymphoblastic) leukemia, and Castleman's disease. NHL may also include T-cell non-Hodgkin's lymphomas (T-NHLs), which include, but are not limited to T-cell non-Hodgkin's lymphoma not otherwise specified (NOS), peripheral T-cell lymphoma (PTCL), anaplastic large cell lymphoma (ALCL), angioimmunoblastic lymphoid disorder (AILD), nasal natural killer (NK) cell/T-cell lymphoma, gamma/delta lymphoma, cutaneous T cell lymphoma, mycosis fungoides, and Sezary syndrome.

Inflammation represents a group of vascular, cellular and neurological responses to trauma. Inflammation can be characterized as the movement of inflammatory cells such as monocytes, neutrophils and granulocytes into the tissues. This is usually associated with reduced endothelial barrier function and oedema into the tissues. Inflammation can be classified as either acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli and is achieved by the increased movement of plasma and leukocytes from the blood into the injured tissues. A cascade of biochemical event propagates and matures the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. Prolonged inflammation, known as chronic inflammation, leads to a progressive shift in the type of cells which are present at the site of inflammation and is characterized by simultaneous destruction and healing of the tissue from the inflammatory process.

When occurring as part of an immune response to infection or as an acute response to trauma, inflammation can be beneficial and is normally self-limiting. However, inflammation can be detrimental under various conditions. This includes the production of excessive inflammation in response to infectious agents, which can lead to significant organ damage and death (for example, in the setting of sepsis). Moreover, chronic inflammation is generally deleterious and is at the root of numerous chronic diseases, causing severe and irreversible damage to tissues. In such settings, the immune response is often directed against self-tissues (autoimmunity), although chronic responses to foreign entities can also lead to bystander damage to self tissues.

The aim of anti-inflammatory therapy is therefore to reduce this inflammation, to inhibit autoimmunity when present, and to allow for the physiological process or healing and tissue repair to progress.

The compounds of this invention may be used to treat inflammation of any tissue and organs of the body, including musculoskeletal inflammation, vascular inflammation, neural inflammation, digestive system inflammation, ocular inflammation, inflammation of the reproductive system, and other inflammation, as exemplified below.

Musculoskeletal inflammation refers to any inflammatory condition of the musculoskeletal system, particularly those conditions affecting skeletal joints, including joints of the hand, wrist, elbow, shoulder, jaw, spine, neck, hip, knee, ankle, and foot, and conditions affecting tissues connecting muscles to bones such as tendons.

Anti-microtubule or anti-mitotic agents are phase specific agents active against the microtubules of tumor cells during M or the mitosis phase of the cell cycle. Examples of anti-microtubule agents include, but are not limited to, diterpenoids and vinca alkaloids.

Diterpenoids, which are derived from natural sources, are phase specific anti -cancer agents that operate at the G₂/M phases of the cell cycle. It is believed that the diterpenoids stabilize the β-tubulin subunit of the microtubules, by binding with this protein. Disassembly of the protein appears then to be inhibited with mitosis being arrested and cell death following. Examples of diterpenoids include, but are not limited to, paclitaxel and its analog docetaxel.

Paclitaxel, 5β,20-epoxy-1,2α,4,7β3,10ρ3,13α-hexa-hydroxytax-11-en-9-one 4,10-diacetate 2-benzoate 13-ester with (2R,3S)—N-benzoyl-3-phenylisoserine; is a natural diterpene product isolated from the Pacific yew tree Taxus brevifolia and is commercially available as an injectable solution TAXOL®.

Intem, Med., 111:273, 1989) and for the treatment of breast cancer (Holmes et al., J. Nat. Cancer Inst., 83:1797, 1991.) It is a potential candidate for treatment of neoplasms in the skin (Einzig et. al., Proc. Am. Soc. Clin. Oncol., 20:46) and head and neck carcinomas (Forastire et. al., Sem. Oncol., 20:56, 1990). The compound also shows potential for the treatment of polycystic kidney disease (Woo et. al., Nature, 368:750. 1994), lung cancer and malaria. Treatment of patients with paclitaxel results in bone marrow suppression (multiple cell lineages, Ignoff, R. J. et. al, Cancer Chemotherapy Pocket Guide, 1998) related to the duration of dosing above a threshold concentration (50 nM) (Kearns, C. M. et. al., Seminars in Oncology, 3(6) p. 16-23, 1995).

Docetaxel, (2R,3S)—N-carboxy-3-phenylisoserine,N-tert-butyl ester, 13-ester with 5β-20-epoxy-1,2α,4,7β,10β,13α-hexahydroxytax-11-en-9-one 4-acetate 2-benzoate, trihydrate; is commercially available as an injectable solution as TAXOTERE®.

Vinca alkaloids are phase specific anti-neoplastic agents derived from the periwinkle plant. Vinca alkaloids act at the M phase (mitosis) of the cell cycle by binding specifically to tubulin. Consequently, the bound tubulin molecule is unable to polymerize into microtubules. Mitosis is believed to be arrested in metaphase with cell death following. Examples of vinca alkaloids include, but are not limited to, vinblastine, vincristine, and vinorelbine.

Vinblastine, vincaleukoblastine sulfate, is commercially available as VELBAN® as an injectable solution.

Antibiotic anti-neoplastics are non-phase specific agents, which bind or intercalate with DNA. Typically, such action results in stable DNA complexes or strand breakage, which disrupts ordinary function of the nucleic acids leading to cell death. Examples of antibiotic anti-neoplastic agents include, but are not limited to, actinomycins such as dactinomycin, anthracyclines such as daunorubicin and doxorubicin; and bleomycins.

Antimetabolite neoplastic agents are phase specific anti-neoplastic agents that act at S phase (DNA synthesis) of the cell cycle by inhibiting DNA synthesis or by inhibiting purine or pyrimidine base synthesis and thereby limiting DNA synthesis. Consequently, S phase does not proceed and cell death follows. Examples of antimetabolite anti-neoplastic agents include, but are not limited to, fluorouracil, methotrexate, cytarabine, mercaptopurine, thioguanine, and gemcitabine.

5-Fluorouracil, 5-fluoro-2,4-(1H,3H) pyrimidinedione, is commercially available as fluorouracil.

Irinotecan is a derivative of camptothecin which binds, along with its active metabolite SN-38, to the topoisomerase I -DNA complex. It is believed that cytotoxicity occurs as a result of irreparable double strand breaks caused by interaction of the topoisomerase I: DNA: irinotecan or SN-38 ternary complex with replication enzymes. Irinotecan is indicated for treatment of metastatic cancer of the colon or rectum.

Topotecan HCl, (S)-10-[(dimethylamino)methyl]-4-ethyl-4,9-dihydroxy-1H-pyrano[3′,4′,6,7]indolizino[1,2-b]quinoline-3,14-(4H,12H)-dione monohydrochloride, is commercially available as the injectable solution HYCAMTIN®.

Nos. 5,681,835, 5,877,219, and 6,207,716, useful in the treatment of hormone dependent breast carcinoma and other susceptible cancers; and gonadotropin-releasing hormone (GnRH) and analogues thereof which stimulate the release of leutinizing hormone (LH) and/or follicle stimulating hormone (FSH) for the treatment prostatic carcinoma, for instance, LHRH agonists and antagonists such as goserelin acetate and luprolide.

Signal transduction pathway inhibitors are those inhibitors, which block or inhibit a chemical process which evokes an intracellular change. As used herein this change is cell proliferation or differentiation. Signal transduction inhibitors useful in the present invention include inhibitors of receptor tyrosine kinases, non-receptor tyrosine kinases, SH2/SH3domain blockers, serine/threonine kinases, phosphotidyl inositol-3 kinases, myo-inositol signaling, and Ras oncogenes.

Several protein tyrosine kinases catalyze the phosphorylation of specific tyrosyl residues in various proteins involved in the regulation of cell growth. Such protein tyrosine kinases can be broadly classified as receptor or non-receptor kinases.

Receptor tyrosine kinases are transmembrane proteins having an extracellular ligand binding domain, a transmembrane domain, and a tyrosine kinase domain. Receptor tyrosine kinases are involved in the regulation of cell growth and are generally termed growth factor receptors. Inappropriate or uncontrolled activation of many of these kinases, i.e. aberrant kinase growth factor receptor activity, for example by over-expression or mutation, has been shown to result in uncontrolled cell growth. Accordingly, the aberrant activity of such kinases has been linked to malignant tissue growth. Consequently, inhibitors of such kinases could provide cancer treatment methods. Growth factor receptors include, for example, epidermal growth factor receptor (EGFr), platelet derived growth factor receptor (PDGFr), erbB2, erbB4, ret, vascular endothelial growth factor receptor (VEGFr), tyrosine kinase with immunoglobulin-like and epidermal growth factor homology domains (TIE-2), insulin growth factor-I (IGFI) receptor, macrophage colony stimulating factor (cfms), BTK, ckit, cmet, fibroblast growth factor (FGF) receptors, Trk receptors (TrkA, TrkB, and TrkC), ephrin (eph) receptors, and the RET protooncogene. Several inhibitors of growth receptors are under development and include ligand antagonists, antibodies, tyrosine kinase inhibitors and anti-sense oligonucleotides. Growth factor receptors and agents that inhibit growth factor receptor function are described, for instance, in Kath, John C., Exp. Opin. Ther. Patents (2000) 10(6):803-818; Shawver et al DDT Vol 2, No. 2 Feb. 1997; and Lofts, F. J. et al, “Growth factor receptors as targets”, New Molecular Targets for Cancer Chemotherapy, ed. Workman, Paul and Kerr, David, CRC press 1994, London.

Tyrosine kinases, which are not growth factor receptor kinases are termed non-receptor tyrosine kinases. Non-receptor tyrosine kinases useful in the present invention, which are targets or potential targets of anti-cancer drugs, include cSrc, Lck, Fyn, Yes, Jak, cAbl, FAK (Focal adhesion kinase), Brutons tyrosine kinase, and Bcr-Abl. Such non-receptor kinases and agents which inhibit non-receptor tyrosine kinase function are described in Sinh, S. and Corey, S. J., (1999) Journal of Hematotherapy and Stem Cell Research 8 (5): 465-80; and Bolen, J. B., Brugge, J. S., (1997) Annual review of Immunology. 15: 371-404.

SH2/SH3 domain blockers are agents that disrupt SH2 or SH3 domain binding in a variety of enzymes or adaptor proteins including, PI3-K p85 subunit, Src family kinases, adaptor molecules (Shc, Crk, Nck, Grb2) and Ras-GAP. SH2/SH3 domains as targets for anti-cancer drugs are discussed in Smithgall, T. E. (1995), Journal of Pharmacological and Toxicological Methods. 34(3) 125-32.

Inhibitors of Serine/Threonine Kinases including MAP kinase cascade blockers which include blockers of Raf kinases (rafk), Mitogen or Extracellular Regulated Kinase (MEKs), and Extracellular Regulated Kinases (ERKs); and Protein kinase C family member blockers including blockers of PKCs (alpha, beta, gamma, epsilon, mu, lambda, iota, zeta). IkB kinase family (IKKa, IKKb), PKB family kinases, akt kinase family members, and TGF beta receptor kinases. Such Serine/Threonine kinases and inhibitors thereof are described in Yamamoto, T., Taya, S., Kaibuchi, K., (1999), Journal of Biochemistry. 126 (5) 799-803; Brodt, P, Samani, A., and Navab, R.

(1995), Cancer Treatment and Research. 78: 3-27, Lackey, K. et al Bioorganic and Medicinal Chemistry Letters, (10), 2000, 223-226; U.S. Pat. No. 6,268,391; and Martinez-Iacaci, L., et al, Int. J. Cancer (2000), 88(1), 44-52.

Inhibitors of Phosphotidyl inositol-3 Kinase family members including blockers of PI3-kinase, ATM, DNA-PK, and Ku are also useful in the present invention. Such kinases are discussed in Abraham, R. T. (1996), Current Opinion in Immunology. 8 (3) 412-8; Canman, C. E., Lim, D. S. (1998), Oncogene 17 (25) 3301-3308; Jackson, S. P. (1997), International Journal of Biochemistry and Cell Biology. 29 (7):935-8; and Zhong, H. et al, Cancer res, (2000) 60(6), 1541-1545.

Also useful in the present invention are Myo-inositol signaling inhibitors such as phospholipase C blockers and Myoinositol analogues. Such signal inhibitors are described in Powis, G., and Kozikowski A., (1994) New Molecular Targets for Cancer Chemotherapy ed., Paul Workman and David Kerr, CRC press 1994, London.

Another group of signal transduction pathway inhibitors are inhibitors of Ras Oncogene. Such inhibitors include inhibitors of farnesyltransferase, geranyl-geranyl transferase, and CAAX proteases as well as anti-sense oligonucleotides, ribozymes and immunotherapy. Such inhibitors have been shown to block ras activation in cells containing wild type mutant ras, thereby acting as antiproliferation agents. Ras oncogene inhibition is discussed in Scharovsky, O. G., Rozados, V. R., Gervasoni, S. I. Matar, P. (2000), Journal of Biomedical Science. 7(4) 292-8; Ashby, M. N. (1998), Current Opinion in Lipidology. 9 (2) 99-102; and BioChim. Biophys. Acta, (19899) 1423(3):19-30.

As mentioned above, antibody antagonists to receptor kinase ligand binding may also serve as signal transduction inhibitors. This group of signal transduction pathway inhibitors includes the use of humanized antibodies to the extracellular ligand binding domain of receptor tyrosine kinases. For example Imclone C225 EGFR specific antibody (see Green, M. C. et al, Monoclonal Antibody Therapy for Solid Tumors, Cancer Treat. Rev., (2000), 26(4), 269-286); Herceptin® erbB2 antibody (see Tyrosine Kinase Signaling in Breast cancer:erbB Family Receptor Tyrosine Kinases, Breast cancer Res., 2000, 2(3), 176-183); and 2CB VEGFR2 specific antibody (see Brekken, R. A. et al, Selective Inhibition of VEGFR2 Activity by a monoclonal Anti-VEGF antibody blocks tumor growth in mice, Cancer Res. (2000) 60, 5117-5124).

Anti-angiogenic therapeutic agents including non-receptor MEK angiogenesis inhibitors may also be useful. Anti-angiogenic agents such as those which inhibit the effects of vascular endothelial growth factor, (for example the anti-vascular endothelial cell growth factor antibody bevacizumab [Avastin™], and compounds that work by other mechanisms (for example linomide, inhibitors of integrin av133 function, endostatin and angiostatin).

Agents used in immunotherapeutic regimens may also be useful in combination with the compounds of Formula (I-N), (I-P) or (I). Immunotherapy approaches, including for example ex-vivo and in-vivo approaches to increase the immunogenecity of patient tumor cells, such as transfection with cytokines such as interleukin 2, interleukin 4 or granulocyte-macrophage colony stimulating factor, approaches to decrease T-cell energy, approaches using transfected immune cells such as cytokine-transfected dendritic cells, approaches using cytokine-transfected tumor cell lines and approaches using anti-idiotypic antibodies.

Therapeutic agents used in proapoptotic regimens (e.g., bcl-2 antisense oligonucleotides) may also be used in the combination of the present invention.

Cell cycle signaling inhibitors inhibit molecules involved in the control of the cell cycle. A family of protein kinases called cyclin dependent kinases (CDKs) and their interaction with a family of proteins termed cyclins controls progression through the eukaryotic cell cycle. The coordinate activation and inactivation of different cyclin/CDK complexes is necessary for normal progression through the cell cycle. Several inhibitors of cell cycle signaling are under development. For instance, examples of cyclin dependent kinases, including CDK2, CDK4, and CDK6 and inhibitors for the same are described in, for instance, Rosania et al, Exp. Opin. Ther. Patents (2000) 10(2):215-230.

Additional examples of other therapeutic agents (anti-neoplastic agent) for use in combination or co-administered with a compound of Formula (I-N), (I-P) or (I) are antibodies to ICOS.

ICOS is a co-stimulatory T cell receptor with structural and functional relation to the CD28/CTLA-4-Ig superfamily (Hutloff, et al., “ICOS is an inducible T-cell co-stimulator structurally and functionally related to CD28”, Nature, 397: 263-266 (1999)). Activation of ICOS occurs through binding by ICOS-L (B7RP-1/B7-H2). Neither B7-1 nor B7-2 (ligands for CD28 and CTLA4) bind or activate ICOS. However, ICOS-L has been shown to bind weakly to both CD28 and CTLA-4 (Yao S et al., “B7-H2 is a costimulatory ligand for CD28 in human”, Immunity, 34(5); 729-40 (2011)). Expression of ICOS appears to be restricted to T cells. ICOS expression levels vary between different T cell subsets and on T cell activation status. ICOS expression has been shown on resting TH17, T follicular helper (TFH) and regulatory T (Treg) cells; however, unlike CD28; it is not highly expressed on naïve T_(H)1 and T_(H)2 effector T cell populations (Paulos C M et al., “The inducible costimulator (ICOS) is critical for the development of human Th17 cells”, Sci Transl Med, 2(55); 55ra78 (2010)). ICOS expression is highly induced on CD4+ and CD8+ effector T cells following activation through TCR engagement (Wakamatsu E, et al., “Convergent and divergent effects of costimulatory molecules in conventional and regulatory CD4+ T cells”, Proc Natal Acad Sci USA, 110(3); 1023-8 (2013)).

CDRs for murine antibodies to human ICOS having agonist activity are shown in PCT/EP2012/055735 (WO 2012/131004). Antibodies to ICOS are also disclosed in WO 2008/137915, WO 2010/056804, EP 1374902, EP1374901, and EP1125585.

CD134, also known as OX40, is a member of the TNFR-superfamily of receptors which is not constitutively expressed on resting naïve T cells, unlike CD28. OX40 is a secondary costimulatory molecule, expressed after 24 to 72 hours following activation; its ligand, OX40L, is also not expressed on resting antigen presenting cells, but is following their activation. Expression of OX40 is dependent on full activation of the T cell; without CD28, expression of OX40 is delayed and of fourfold lower levels.

Thus, in one embodiment methods of treating a human in need thereof are provided comprising administering a compound of Formula (I-N), (I-P) or (I) or a salt thereof and at least one immuno-modulator. In one embodiment, the immuno-modulator is selected from an ICOS agonist antibody, an OX-40 antibody or a PD-1 antibody. In one embodiment, the human has cancer. Also provided herein is the use of a compound of Formula (I-N), (I-P) or (I), or a salt thereof in combination with at least one immuno-modulator for the treatment of a human in need thereof.

Additional examples of other therapeutic agents for use in combination or co-administered with a compound of Formula (I-N), (I-P) or (I), or a salt thereof are immunostimulatory agents.

As used herein “immunostimulatory agent” refers to any agent that can stimulate the immune system. As used herein immunostimulatory agents include, but are not limited to, vaccine adjuvants, such as Toll-like receptor agonists, T-cell checkpoint blockers, such as mAbs to PD-1 and CTL4 and T-cell checkpoint agonist, such as agonist mAbs to OX-40 and ICOS. As used herein “immunostimulatory agent” refers to any agent that can stimulate the immune system. As used herein immunostimulatory agents include, but are not limited to, vaccine adjuvants.

The term “Toll-like receptor” (or “TLR”) as used herein refers to a member of the Toll-like receptor family of proteins or a fragment thereof that senses a microbial product and/or initiates an adaptive immune response. In one embodiment, a TLR activates a dendritic cell (DC). Toll-like receptors (TLRs) are a family of pattern recognition receptors that were initially identified as sensors of the innate immune system that recognize microbial pathogens. TLRs recognize distinct structures in microbes, often referred to as “PAMPs” (pathogen associated molecular patterns). Ligand binding to TLRs invokes a cascade of intra-cellular signaling pathways that induce the production of factors involved in inflammation and immunity. In humans, ten TLR have been identified. TLRs that are expressed on the surface of cells include TLR-1, -2, -4, -5, and -6, while TLR-3, -7/8, and -9 are expressed with the ER compartment. Human DC subsets can be identified on the basis of distinct TLR expression patterns. By way of example, the myeloid or “conventional” subset of DC (mDC) expresses TLRs 1-8 when stimulated, and a cascade of activation markers (e.g. CD80, CD86, MHC class I and II, CCR7), pro-inflammatory cytokines, and chemokines are produced. A result of this stimulation and resulting expression is antigen-specific CD4+ and CD8+ T cell priming. These DCs acquire an enhanced capacity to take up antigens and present them in an appropriate form to T cells. In contrast, the plasmacytoid subset of DC (pDC) expresses only TLR7 and TLR9 upon activation, with a resulting activation of NK cells as well as T-cells. As dying tumor cells may adversely affect DC function, it has been suggested that activating DC with TLR agonists may be beneficial for priming anti-tumor immunity in an immunotherapy approach to the treatment of cancer. It has also been suggested that successful treatment of breast cancer using radiation and chemotherapy requires TLR4 activation.

TLR agonists known in the art and finding use in the present invention include, but are not limited to, the following: Pam3Cys, a TLR1/2 agonist; CFA, a TLR2 agonist; MALP2, a TLR2 agonist; Pam2Cys, a TLR2 agonist; FSL-I, a TLR-2 agonist; Hib-OMPC, a TLR-2 agonist; polyinosinic:polycytidylic acid (Poly I:C), a TLR3 agonist; polyadenosine-polyuridylic acid (poly AU), a TLR3 agonist; Polyinosinic-Polycytidylic acid stabilized with poly-L-lysine and carboxymethylcellulose (Hiltonol), a TLR3 agonist; bacterial flagellin a TLR5 agonist; imiquimod, a TLR7 agonist; resiquimod, a TLR7/8 agonist; loxoribine, a TLR7/8 agonist; and unmethylated CpG dinucleotide (CpG-ODN), a TLR9 agonist.

Additional TLR agonists known in the art and finding use in the present invention further include, but are not limited to aminoalkyl glucosaminide phosphates (AGPs) which bind to the TLR4 receptor are known to be useful as vaccine adjuvants and immunostimulatory agents for stimulating cytokine production, activating macrophages, promoting innate immune response, and augmenting antibody production in immunized animals. An example of a naturally occurring TLR4 agonist is bacterial LPS. An example of a semisynthetic TLR4 agonist is monophosphoryl lipid A (MPL). AGPs and their immunomodulating effects via TLR4 are disclosed in patent publications such as WO 2006/016997, WO 2001/090129, and/or U.S. Pat. No. 6,113,918 and have been reported in the literature. Additional AGP derivatives are disclosed in U.S. Pat. No. 7,129,219, U.S. Pat. No. 6,525,028 and U.S. Pat. No. 6,911,434. Certain AGPs act as agonists of TLR4, while others are recognized as TLR4 antagonist.

In one embodiment the immunostimulatory agent for use in combination with the compounds of the present invention is a TLR4 agonist. In one embodiment, the TLR4 agonist are referred to as CRX-601 and CRX-527. Their structures are set forth as follows:

Additionally, another preferred embodiment employs the TLR4 agonist CRX 547 having the structure shown.

Still other embodiments include AGPs such as CRX 602 or CRX 526 providing increased stability to AGPs having shorter secondary acyl or alkyl chains.

Thus, in one embodiment, methods of treating a human in need thereof are provided comprising administering a compound of Formula (I-N), (I-P) or (I) or a salt thereof and at least one immunostimulatory agent. In one embodiment, the immunostimulatory agent is a TLR4 agonist. In one embodiment, the immunostimulatory agent is an AGP. In yet another embodiment, the TLR4 agonist is selected from a compound having the formula CRX-601, CRX-527, CRX-547, CRX-602 or CRX-526. In one embodiment, the human has cancer. Also provided herein is the use a compound of Formula (I-N), (I-P) or (I), or a salt thereof in combination with at least one immunestimulatory agent for the treatment of a human in need thereof.

In addition to the immunostimulatory agents described above, the compositions of the present invention may further comprise other therapeutic agents which, because of their adjuvant nature, can act to stimulate the immune system to respond to the cancer antigens present on the inactivated tumor cell(s). Such adjuvants include, but are not limited to, lipids, liposomes, inactivated bacteria which induce innate immunity (e.g., inactivated or attenuated Listeriamonocytogenes), compositions which mediate innate immune activation via, (NOD)-like receptors (NLRs), Retinoic acid inducible gene-based (RIG)-I-like receptors (RLRs), and/or C-type lectin receptors (CLRs). Examples of PAMPs include lipoproteins, lipopolypeptides, peptidoglycans, zymosan, lipopolysaccharide, neisserial porins, flagellin, profillin, galactoceramide, muramyl dipeptide. Peptidoglycans, lipoproteins, and lipoteichoic acids are cell wall components of Gram-positive. Lipopolysaccharides are expressed by most bacteria, with MPL being one example. Flagellin refers to the structural component of bacterial flagella that is secreted by pathogenic and commensal bacteria. rt.-Galactosylceramide (rt.-GalCer) is an activator of natural killer T (NKT) cells. Muramyl dipeptide is a bioactive peptidoglycan motif common to all bacteria.

Because of their adjuvant qualities, TLR agonists are preferably used in combinations with other vaccines, adjuvants and/or immune modulators, and may be combined in various combinations. Thus, in certain embodiments, the herein described compounds of Formula (I-N), (I-P) or (I) that bind to STING and induce STING-dependent TBKI activation and an inactivated tumor cell which expresses and secretes one or more cytokines which stimulate DC induction, recruitment and/or maturation, as described herein can be administered together with one or more TLR agonists for therapeutic purposes.

Indoleamine 2,3-dioxygenase 1 (IDO1) is a key immunosuppressive enzyme that modulates the anti-tumor immune response by promoting regulatory T cell generation and blocking effector T cell activation, thereby facilitating tumor growth by allowing cancer cells to avoid immune surveillance. (Lemos H, et al., Cancer Res. 2016 Apr. 15; 76(8):2076-81), (Munn D H, et al., Trends Immunol. 2016 March; 37(3):193-207).

In a further aspect of the invention, there is provided a vaccine adjuvant comprising a compound of Formula (I-N), (I-P) or (I), or a pharmaceutically acceptable salt thereof. There is further provided a vaccine composition comprising a compound of Formula (I-N), (I-P) or (I), or a pharmaceutically acceptable salt thereof, and an antigen or antigen composition.

A therapeutically “effective amount” is intended to mean that amount of a compound that, when administered to a patient in need of such treatment, is sufficient to effective treat or prevent, as defined herein. Thus, e.g., a therapeutically effective amount of a compound of Formula (I-N), (I-P) or (I), or a pharmaceutically acceptable salt thereof, is a quantity of an inventive agent that, when administered to a human in need thereof, is sufficient to modulate the activity of STING such that a disease condition which is mediated by that activity is reduced, alleviated or prevented. The amount of a given compound that will correspond to such an amount will vary depending upon factors such as the particular compound (e.g., the potency (pIC₅₀), efficacy (EC₅₀), and the biological half-life of the particular compound), disease condition and its severity, the identity (e.g., age, size and weight) of the patient in need of treatment, but can nevertheless be routinely determined by one skilled in the art. Likewise, the duration of treatment and the time period of administration (time period between dosages and the timing of the dosages, e.g., before/with/after meals) of the compound will vary according to the identity of the mammal in need of treatment (e.g., weight), the particular compound and its properties (e.g., pharmacokinetic properties), disease or disorder and its severity and the specific composition and method being used, but can nevertheless be determined by one of skill in the art.

“Treating” or “treatment” is intended to mean at least the mitigation of a disease or disorder in a patient. The methods of treatment for mitigation of a disease or disorder include the use of the compounds in this invention in any conventionally acceptable manner, for example for retardation, therapy or cure of a STING-mediated disease or disorder, as described hereinabove. In one embodiment, “treat” “treating” or “treatment” in reference to cancer refers to alleviating the cancer, eliminating or reducing one or more symptoms of the cancer, slowing or eliminating the progression of the cancer, and delaying the reoccurrence of the condition in a previously afflicted or diagnosed patient or subject.

“Prevent”, “preventing” or “prevention” refers to the prophylactic administration of a drug to diminish the likelihood of the onset of or to delay the onset of a disease or biological manifestation thereof. Prophylactic therapy is appropriate, for example, when a subject is considered at high risk for developing cancer, such as when a subject has a strong family history of cancer or when a subject has been exposed to a carcinogen.

The compounds of the invention may be administered by any suitable route of administration, including both systemic administration and topical administration. Systemic administration includes oral administration, parenteral administration, transdermal administration, rectal administration, and administration by inhalation. Parenteral administration refers to routes of administration other than enteral, transdermal, or by inhalation, and is typically by injection or infusion. Parenteral administration includes intravenous, intramuscular, and subcutaneous injection or infusion. Inhalation refers to administration into the patient's lungs whether inhaled through the mouth or through the nasal passages. Topical administration includes application to the skin.

In addition to the above described routes of administration suitable for treatment of oncology, the pharmaceutical compositions may be adapted for administration by intratumoral or peritumoral injection. The intratumoral or peritumoral injection of a compound of the present invention directly into or adjacent to a single solid tumor is expected to elicit an immune response that can attack and destroy cancer cells throughout the body, substantially reducing and in some cases permanently eliminating the tumor from the diseased subject. The activation of the immune system in this manner to kill tumors at a remote site is commonly known as the abscopal effect and has been demonstrated in animals with multiple therapeutic modalities, (van der Jeught, et al., Oncotarget, 2015, 6(3), 1359-1381). A further advantage of local or intratumoral or peritumoral administration is the ability to achieve equivalent efficacy at much lower doses, thus minimizing or eliminating adverse events that may be observed at much higher systemic doses (Marabelle, A., et al., Clinical Cancer Research, 2014, 20(7), p 1747-1756).

The compounds of the invention may be administered once or according to a dosing regimen wherein a number of doses are administered at varying intervals of time for a given period of time. For example, doses may be administered one, two, three, or four times per day. Doses may be administered until the desired therapeutic effect is achieved or indefinitely to maintain the desired therapeutic effect. Suitable dosing regimens for a compound of the invention depend on the pharmacokinetic properties of that compound, such as absorption, distribution, and half-life, which can be determined by the skilled artisan. In addition, suitable dosing regimens, including the duration such regimens are administered, for a compound of the invention depend on the disease or disorder being treated, the severity of the disease or disorder being treated, the age and physical condition of the patient being treated, the medical history of the patient to be treated, the nature of concurrent therapy, the desired therapeutic effect, and like factors within the knowledge and expertise of the skilled artisan. It will be further understood by such skilled artisans that suitable dosing regimens may require adjustment given an individual patient's response to the dosing regimen or over time as individual patient needs change. Total daily dosages range from 1 mg to 2000 mg, preferably, total daily dosages range from 1 mg to 250 mg.

For use in therapy, the compounds of the invention will be normally, but not necessarily, formulated into a pharmaceutical composition prior to administration to a patient. Accordingly, the invention also is directed to pharmaceutical compositions comprising a compound of the invention and at least one pharmaceutically acceptable excipient.

The pharmaceutical compositions of the invention may be prepared and packaged in bulk form wherein an effective amount of a compound of the invention can be extracted and then given to the patient such as with powders, syrups, and solutions for injection. Alternatively, the pharmaceutical compositions of the invention may be prepared and packaged in unit dosage form. For oral application, for example, one or more tablets or capsules may be administered. A dose of the pharmaceutical composition contains at least a therapeutically effective amount of a compound of this invention (i.e., a compound of Formula (I-N), (I-P) or (I), or a salt, particularly a pharmaceutically acceptable salt, thereof). When prepared in unit dosage form, the pharmaceutical compositions may contain from 1 mg to 1000 mg of a compound of this invention.

As provided herein, unit dosage forms (pharmaceutical compositions) containing from 1 mg to 1000 mg of a compound of the invention may be administered one, two, three, or four times per day, preferably one, two, or three times per day, and more preferably, one or two times per day, to effect treatment of a STING-mediated disease or disorder.

The pharmaceutical compositions of the invention typically contain one compound of the invention. However, in certain embodiments, the pharmaceutical compositions of the invention contain more than one compound of the invention. In addition, the pharmaceutical compositions of the invention may optionally further comprise one or more additional therapeutic agents, (e.g., pharmaceutically active compounds).

As used herein, “pharmaceutically acceptable excipient” refers to a pharmaceutically acceptable material, composition or vehicle involved in giving form or consistency to the pharmaceutical composition. Each excipient must be compatible with the other ingredients of the pharmaceutical composition when commingled such that interactions which would substantially reduce the efficacy of the compound of the invention when administered to a patient and interactions which would result in pharmaceutical compositions that are not pharmaceutically acceptable are avoided. In addition, each excipient must of course be of sufficiently high purity to render it pharmaceutically acceptable.

The compounds of the invention and the pharmaceutically acceptable excipient or excipients will typically be formulated into a dosage form adapted for administration to the patient by the desired route of administration. Conventional dosage forms include those adapted for (1) oral administration such as tablets, capsules, caplets, pills, troches, powders, syrups, elixirs, suspensions, solutions, emulsions, sachets, and cachets; (2) parenteral administration such as sterile solutions, suspensions, and powders for reconstitution; (3) transdermal administration such as transdermal patches; (4) rectal administration such as suppositories; (5) inhalation such as aerosols and solutions; and (6) topical administration such as creams, ointments, lotions, solutions, pastes, sprays, foams, and gels.

Suitable pharmaceutically acceptable excipients will vary depending upon the particular dosage form chosen. In addition, suitable pharmaceutically acceptable excipients may be chosen for a particular function that they may serve in the composition. For example, certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of uniform dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the production of stable dosage forms. Certain pharmaceutically acceptable excipients may be chosen for their ability to facilitate the carrying or transporting the compound or compounds of the invention once administered to the patient from one organ, or portion of the body, to another organ, or portion of the body. Certain pharmaceutically acceptable excipients may be chosen for their ability to enhance patient compliance.

Suitable pharmaceutically acceptable excipients include the following types of excipients: diluents, fillers, binders, disintegrants, lubricants, glidants, granulating agents, coating agents, wetting agents, solvents, co-solvents, suspending agents, emulsifiers, sweeteners, flavoring agents, flavor masking agents, coloring agents, anti-caking agents, humectants, chelating agents, plasticizers, viscosity increasing agents, antioxidants, preservatives, stabilizers, surfactants, and buffering agents. The skilled artisan will appreciate that certain pharmaceutically acceptable excipients may serve more than one function and may serve alternative functions depending on how much of the excipient is present in the formulation and what other ingredients are present in the formulation.

Skilled artisans possess the knowledge and skill in the art to enable them to select suitable pharmaceutically acceptable excipients in appropriate amounts for use in the invention. In addition, there are a number of resources that are available to the skilled artisan which describe pharmaceutically acceptable excipients and may be useful in selecting suitable pharmaceutically acceptable excipients. Examples include Reminaton's Pharmaceutical Sciences (Mack Publishing Company), The Handbook of Pharmaceutical Additives (Gower Publishing Limited), and The Handbook of Pharmaceutical Excipients (the American Pharmaceutical Association and the Pharmaceutical Press).

The pharmaceutical compositions of the invention are prepared using techniques and methods known to those skilled in the art. Some of the methods commonly used in the art are described in Remington's Pharmaceutical Sciences (Mack Publishing Company).

In one aspect, the invention is directed to a solid oral dosage form such as a tablet or capsule comprising an effective amount of a compound of the invention and a diluent or filler. Suitable diluents and fillers include lactose, sucrose, dextrose, mannitol, sorbitol, starch (e.g. corn starch, potato starch, and pre-gelatinized starch), cellulose and its derivatives (e.g. microcrystalline cellulose), calcium sulfate, and dibasic calcium phosphate.

The oral solid dosage form may further comprise a binder. Suitable binders include starch (e.g. corn starch, potato starch, and pre-gelatinized starch), gelatin, acacia, sodium alginate, alginic acid, tragacanth, guar gum, povidone, and cellulose and its derivatives (e.g. microcrystalline cellulose). The oral solid dosage form may further comprise a disintegrant. Suitable disintegrants include crospovidone, sodium starch glycolate, croscarmelose, alginic acid, and sodium carboxymethyl cellulose. The oral solid dosage form may further comprise a lubricant. Suitable lubricants include stearic acid, magnesium stearate, calcium stearate, and talc. For example, tablets may be prepared using conventional methods and are formulated as follows: Compound, 5 mg; Microcrystalline cellulose, 100 mg; Lactose, 100 mg; Sodium starch glycollate, 30 mg; Magnesium stearate, 2 mg; Total wt. 237 mg. Capsules may be prepared using conventional methods and are formulated as follows: Compound, 15 mg; dried starch, 178 mg; Magnesium stearate, 2 mg; Total wt. 195 mg.

It will be understood that the compounds of this invention may also be formulated with vaccines as adjuvants to modulate their activity. Such compositions may contain antibody (antibodies) or antibody fragment(s) or an antigenic component including but not limited to protein, DNA, live or dead bacteria and/or whole, inactivated or split viruses or virus-like particles, recombinant proteins or antigenic fragments thereof, optionally together with one or more other components with adjuvant activity including but not limited to aluminum salts, oil and water emulsions, heat shock proteins, saponins, lipid A preparations and derivatives, glycolipids, liposomes, TLR agonists such as CpG DNA or similar agents, cytokines such as GM-CSF or IL-12, or similar agents.

Certain compounds of the invention may be potent immunomodulators and accordingly, care should be exercised in their handling.

These examples are not intended to limit the scope of the present invention, but rather to provide guidance to the skilled artisan to prepare and use the compounds, compositions, and methods of the present invention. While particular embodiments of the present invention are described, the skilled artisan will appreciate that various changes and modifications can be made without departing from the spirit and scope of the invention.

It will be understood that certain compounds of the invention may be potent immunomodulators and accordingly, care should be exercised in their handling.

The reactions described herein are applicable for producing compounds of the invention having a variety of different substituent groups (e.g., R¹, R², etc.), as defined herein. The skilled artisan will appreciate that if a particular substituent is not compatible with the synthetic methods described herein, the substituent may be protected with a suitable protecting group that is stable to the reaction conditions. Suitable protecting groups and the methods for protecting and de-protecting different substituents using such suitable protecting groups are well known to those skilled in the art; examples of which may be found in T. W. Greene ‘Protective Groups in Organic Synthesis’ (4th edition, J. Wiley and Sons, 2006). Unless otherwise noted, all starting materials were obtained from commercial suppliers and used without further purification.

Certain intermediate compounds described herein form a yet further aspect of the invention.

General Synthetic Methods

The compounds of this invention may be prepared using synthetic procedures illustrated in the reaction schemes below, which can be readily adapted to prepare other compounds of the invention by drawing on the knowledge of a skilled organic chemist. The syntheses provided in these schemes are applicable for producing compounds of the invention having a variety of different R groups employing appropriate precursors, which are suitably protected if needed, to achieve compatibility with the reactions outlined herein.

Subsequent deprotection, where needed, affords compounds of the nature generally disclosed. While the schemes are shown with compounds only of Formula (I-N), (I-P) or (I), they are illustrative of processes that may be used to make the compounds of the invention. Intermediates (compounds used in the preparation of the compounds of the invention) may also be present as salts.

Method 1: An appropriate nitro-halo benzamide (1A) may be treated with an amine (allylamine used as an example) under base or metal-mediated coupling conditions to afford the aniline (1B). Subsequent reduction of the nitro group via appropriate conditions will provide dianiline (1C). Reaction with cyanogen bromide provides the aminobenzimidazole (1D). Peptide coupling between the aminobenzimiazole and pyrazole acid (1E) generates the amidobenzimidazole monomer (1F). Cross metathesis reaction between two molecules of (1F) affords the unsaturated dimer (1G), which can be hydrogenated to afford saturated dimer 1H.

Method 1

Method 2: Two molecules of an appropriate nitro-halo benzamide (2A) may be treated with a diamine under base or metal-mediated coupling conditions to afford the biscoupled aniline (2B). Subsequent bis-reduction of the nitro groups via appropriate conditions can provide the dianiline (2C). Reaction with cyanogen bromide provides the aminobenzimidazole dimer (2D). Peptide coupling between bis amine (2D) and two molecules of pyrazole acid (2E) generates the amidobenzimidazole dimer (2F).

Method 2

Method 3: Fluoronitrobenzamide (3A) is treated with a monoprotected diamine under base or metal-mediated coupling conditions to afford the aniline (3B). Subsequent reduction of the nitro group via appropriate conditions can provide the dianiline (3C). Reaction with cyanogen bromide provides the aminobenzimidazole (3D).

Method 4

Method 5 Two molecules of an appropriate phenol (5A) are reacted with a bis-electrophile such as dibromopropane to provide ether linked dimer (5B). Dimer (5B) is then reacted with a suitable diamine to afford macrocycle (5C). Reduction of the nitro groups, followed by treatment with cyanogen bromide affords bisaminobenzimidazole (5D). Amide coupling with an appropriate acid (5E) affords bisamidobenzimidazole macrocycle (5F).

Method 5

Method 6

Method 7: Bispyrazole acid 7A (Method 8) is reacted with two molecules of aminobenzimidazole (7B) under amide coupling conditions to afford pyrazole-linked dimer (7C). Ring closing metathesis reaction will afford the unsaturated macrocycle (7D), which can be hydrogenated to provide the saturated amidobenzimidazole macrocycle (7E).

Method 7

Method 8: A substituted (pent-4-yn-1-yl)-1H-pyrazole-carboxylate (8C) may be formed by N-alkylation of a substituted 1H-pyrazole-carboxylate (8A) with (5-chloropent-1-yn-1-yl)trimethylsilane followed by de-silylation. A 4iodo-1H-pyrazole-carboxylate (8F) may be formed by esterification of the corresponding 1H-pyrazole-carboxylic acid (8D), followed by iodination using 1-iodopyrrolidine-2,5-dione. Palladium catalyzed coupling of the substituted (pent-4-yn-1-yl)-1H-pyrazole-carboxylate (8C) with the 4-iodo-1H-pyrazole-carboxylate (8F) forms an alkynyl-linked bispyrazole (8G). Hydrogenation of the alkynyl-linked bispyrazole, followed by hydrolysis provided the bispyrazole acid used in Methods 6 and 7 (6A/7A), above.

Method 8

Method 9: An appropriate nitro-halo benzamide (9A) may be treated with a monoprotected diamine (such as 9B) under base or metal-mediated coupling conditions to afford the coupled aniline (9C). Subsequent deprotection of the primary amine will provide amine 9D. A second nitro-halo benzamide (9E) may be reacted with amine 9D under base or metal-mediated coupling conditions to afford a bis-nitro dimeric benzamide (9F). Double reduction of the nitro groups via appropriate conditions can provide the dianiline (9G). Reaction with cyanogen bromide provides the aminobenzimidazole dimer (9H). Peptide coupling between bis amine 9H and two molecules of pyrazole acid (9I) generates the amidobenzimidazole dimer (9J).

Method 9

Method 10: A tetraaniline (10A, prepared by method 9 or another general method) may be treated with isothiocyanate (10B) until completion of the reaction. Upon completion of step 1, EDC (or other suitable coupling reagent) and triethylamine (or other suitable base) are added and the reaction stirred until completion to afford amidobenzimidazole dimer (10C).

Method 10

Method 11: All variables are as defined in Formula (I-N), (I-P) or Formula (I). A suitably substituted halonitrobenzamide (11A) is reacted with a monoprotected diamine such as 11B to provide nitroaniline 11C. Deprotection of the amine protecting group affords amine 11D, which can be reacted with a halo-nitrophenyl compound 11E to afford bis-nitro 11F. Reduction of both nitro groups will provide a bis-aniline 11G which is treated with cyanogen bromide to afford bisaminobenzimidazole 11H. Amide coupling with a pyrazole acid such as 11I will afford a substituted amidobenzimidazole dimer 11J. When suitable functional groups are present on 11J, further functionalization of these groups will be possible to afford additional compounds such as 11K.

Method 11

Method 12: In method 12, R^(C2)═R¹⁴, R¹⁷═R¹⁵ and R¹⁶═R1, all other variables are as defined in Formula (I-N), Formula (I-P) or Formula (I). A tetraaniline (12A, prepared by method 11, 16 or another general method) may be treated with an isothiocyanate such as 12B until completion of the reaction. Upon completion of step 1, EDC (or other suitable coupling reagent) and triethylamine (or other suitable base) are added and the reaction stirred until completion to afford amidobenzimidazole dimer (12C).

Method 12

Method 13: In method 13, all variables are as defined in Formula (I-N), Formula (I-P) or Formula (I). Macrocyclic compounds with substitutions can be prepared via this method. A substituted halonitrophenyl compound (13A) is treated with a suitable diamine (13B) containing a linker group (B) between the two amine groups to afford amine 13C.

Reduction of the nitro group followed by treatment with cyanogen bromide can afford aminobenzimidazole 13D. Amide coupling between 13D and a mono-carboxylic acid bispyrazole (such as 13E) containing a linker group (C) between the two pyrazoles will afford an amidobenzimidazole (13F). Deprotection of the amine group enables addition to a second substituted halo-nitro-phenyl (13G) to provide nitro-ester 13H. Reduction of the nitro group of 13H followed by treatment with cyanogen bromide will provide aminobenzimidazole 13I. Hydrolysis of the pyrazole ester then enables a macrocyclic amide formation to provide the macrocyclic amidobenzimidazole 13J. When suitable functional groups are present on 13J, further functionalization of these groups will be possible to afford additional compounds such as 13K.

In the case of using with (5-chloropent-1-yn-1-yl)trimethylsilane, a subsequent desilation will afford pyrazole ester 24D. A 4-iodo-pyrazole ester (24G) may be formed by esterification of the corresponding pyrazole-carboxylic acid (24E), followed by iodination using 1-iodopyrrolidine-2,5-dione (NIS). Palladium-catalyzed coupling of an alkylated pyrazole such as 24D with the 4-iodo-pyrazole-ester (24G) forms a linked bispyrazole (24H). Reduction and hydrogenolysis of the linked bispyrazole will provide a bispyrazole monoacid (24I), which can be further hydrolyzed to afford a bispyrazole di acid 24J.

To this was added a solution of (9H-fluoren-9-yl)methyl (2-aminoethyl)carbamate hydrochloride (6.9 mg, 0.022 mmol) and HATU (7.6 mg, 0.020 mmol) in DMSO (100 μL) followed by DIEA (10 μL, 0.057 mmol). After stirring overnight, the reaction was diluted with DMF (600 μL), 4-methylpiperidine (400 μL) was added and the reaction was stirred at RT 1 hr. The mixture was concentrated, and the resulting residue diluted with 1:1 DMSO: MeOH (<1 mL) and purified by reverse-phase chromatography (Jupiter C18 preparative column, 10 mL/min), eluting with 30-100% (9:1 ACN: water) in water (0.1% TFA additive) to yield the title compound (8.45 mg, 10.1 μmol, 69% yield).

The commercial Alexa Fluor 488-ONSu reagent was a mixture of the 5- and 6-positional isomers.

When solution was effected, DIPEA (2 μL, 0.01 mmol) was added, and the mixture was agitated (by vortex action) overnight in the absence of light. LCMS revealed formation of early and late eluting product peaks with the anticipated molecular weight ([M+H] 1238.6). The reaction was concentrated, and the residue was dissolved in 1:1 DMSO: MeOH (<1 mL) and purified by reverse-phase chromatography (Jupiter C18 preparative column, 10 mL/min), eluting with 15-100% (9:1 ACN: water) in water (0.1% TFA additive). The early eluting positional isomer was obtained in high purity. In contrast, the fractions of the late eluting isomer also contained unreacted starting material. These fractions containing the impure late eluting isomer were pooled and concentrated. This residue was dissolved in 1:1 DMSO: MeOH (<1 mL) and purified by reverse-phase chromatography (Waters SymmetryPrep preparative column, 10 mL/min), eluting with 15-100% (9:1 ACN: water) in water (0.1% TFA additive) to yield the title compound (late eluting isomer, 1.94 mg, 1.49 μmol, 19% yield). LCMS (LCMS Method H): Rt=0.69 min, [M+H]⁺=1238.6. Note that the putative structure of the title compound (5-isomer) is not based on rigorous structural determination but instead is based on previous observations that the 5-positional isomer is typically the later eluting isomer by reverse phase HPLC methods.

Binding Assays

(1) SPA

A radioligand binding assay was developed to measure quantitate interactions of compounds of Formula (I-N), (I-P) or (I) and the carboxy terminal domain (CTD) of STING by competition with 3H-cGAMP (tritium-labeled cyclic guanine (2′,5′) monophosphate-adenine (3′,5′) monophosphate). See also Li et al. (Nature Chemical Biology, 10, 1043-1048, (2014)). A protein encoding the sequence of human STING spanning residues 149 to 379 (Gene ID 340061) was expressed in bacteria with a carboxy terminal Flag® peptide fused to AviTag™ for biotinylation and hexahistidine tag for affinity purification. The purified STING-Flag-AviTag-6×his protein was biotinylated to completion using the enzyme BirA (Beckett D. et al, Protein Science, 1999, 8:921-929). The relative potency of compounds of Formula (I-N), (I-P) or (I) were determined by competition in equilibrium binding reactions containing 50 nM biotinylated-STING, 50 nM 3H-cGAMP, and 1.25 mg/mL streptavidin-coated scintilation proximity assay beads (Perkin Elmer) in phosphate-buffered saline buffer. Binding reactions were incubated at room temperature for 30 minutes and read using a luminescence plate reader. Dose response curves were normalized to a control that reflect complete inhibition of 3H-cGAMP binding by 10 μM unlabeled cGAMP and no compound control. The apparent pIC₅₀ was determined using a conventional two-state binding model. Under these conditions, the apparent inhibition constant for positive control compound cGAMP is 40-50 nM which is approximately ten-fold greater than its actual affinity of 4-5 nM (Zhang X et al, Molecular Cell, 2013, 51:1-10).

(2) FRET Assay

The binding potency of molecules to the C-terminal Domain (CTD) of human STING was determined using a competition binding assay. In this assay, STING (149-379) recombinant protein with a C-terminal biotinylated Avi-tag was employed. When bound to STING, an Alexa488-labeled active site probe (see pages 226-229 for the synthesis for the FRET assay ligand) accepts the 490 nm emission from Tb-Streptavidin-Avi-STING and an increase in fluorescence is measured at 520 nm. Molecules that compete for the probe binding site will result in a low 520 nm signal. The assay was run in Greiner black 384-well plates (Catalog #784076) containing 100 nL compounds in neat DMSO. A solution of 500 pM STING, 500 pM Streptavidin-Lumi4-Tb, and 100 nM Alexa488 probe in phosphate buffered saline containing 0.02% (w/v) pluronic F127 and 0.02% (w/v) bovine serum albumin was added to the plate using a Combi liquid handler (ThermoFisher). Plates were centrifuged for 1 min at 500 rpm, incubated for 15 min at room temperature, and then fluorescence emission at 520 nm following 337 nm laser excitation on an Envision plate reader (Perkin-Elmer) was measured. The pIC₅₀ values were determined using a standard four parameter curve fit in ABASE XE.

Using the SPA assay described above, the compounds of Examples 1-9, 11, 13, 15, 16, 23, 25-30, 33-35, 47, 49, 50, 54, 55, 57-61, 63-66, 68-74, 76-79, 81-83, 85-88, 90, 92, 102, 104, 105, 107-110, 112-114, 117, 118, 120, 122-144, 146-149, 151-160, 163-167, 169, 170, 172-183, and 186-197 exhibited pIC₅₀ ovalues in the range of 3.6 to 7.7. For example, the compounds of Example 1 and Example 5, above, inhibited binding of 3H-cGAMP to STING in the above method with mean pIC₅₀ of 7.5 (#1, n=4; #5, n=2).

Using the FRET assay described above, Examples 1-106, 110, 112-125, 129, 131, 133, 134, 138, 142-144, 146-153, 155-186, 188-193, and 196 exhibited pIC₅₀ values in the range of 4.1 to beyond the upper limit of the assay at 9.9. For example, pIC₅₀ of FRET assay for following examples are:

The function of compounds of Formula (I) may be determined in cellular assays that detect STING specific activation and/or inhibition of IFNβ protein secretion.

-   (1) Functional Assay I (PBMC antagonist assay): Inhibition of STING     by compounds of Formula (I-N), (I-P) or (I) may be determined by     measuring loss of interferon β secreted from PBMCs stimulated with     Bacmam virus, a double stranded DNA virus, following treatment with     different doses of compounds of Formula (I-N), (I-P) or (I). Frozen     PBMC cells were thawed and diluted in media (RPMI-1640 with 1.5 g/L     NaHCO₃, 4.5 g/L glucose, 10 mM Hepes and 1 mM NaPyruvate, 10% FBS)     to a final concentration of 5×10⁵ cells/mL followed by infection     with Bacmam virus at a final MOI of 43. The PBMC-Bacmam virus     suspension was dispensed into a 384-well tissue culture plate     (Griener 781073) at a density of 25,000 cells per well containing     250 nL of compound diluted in DMSO. The level IFNβ protein secreted     into the growth media was measured after 24 hours of incubation at     37° C. using a human IFNβ electrochemiluminescence kit (Meso Scale     Diagnostics) following the manufacturer's instructions. Percent     inhibition was determined relative to controls that lack compound     treatment or Bacmam virus infection and plotted as a function of     compound concentration to determine pIC₅₀ using a standard two-state     model of receptor-ligand inhibition. -   (2) Functional Assay II (PBMC agonist assay): Activation of STING by     compounds of Formula I was determined by measuring levels of IFNβ     secreted from human peripheral blood mononuclear cells (PBMC)     treated with different doses of compounds of Formula I. Frozen PBMC     cells were thawed, resuspended in media (RPMI-1640 with 1.5 g/L     NaHCO₃, 4.5 g/L glucose, 10 mM Hepes and 1 mM NaPyruvate, 10% FBS,     10 ng/mL lipopolysaccharide) to a final concentration of 5×10⁵     cells/mL and dispensed into a 384-well tissue culture plate     (Griener 781073) at a density of 15,000 cells per well containing     250 nL of compound diluted in DMSO. The level of IFNβ protein     secreted into the growth media was measured after three hours of     incubation at 37° C. using a human IFNβ electrochemiluminescence kit     (Meso Scale Diagnostics) following the manufacturer's instructions.     Percent activation was determined relative to control DMSO treatment     and plot as a function of compound concentration to determine pEC50     using a standard model of receptor activation. -   (3) Functional Assay III (HEK WT agonist assay): Activation of STING     in cells may be determined using a luciferase reporter assay in     human embryonic kidney cells (HEK293T) co-transfected with plasmids     expressing STING and the enzyme firefly luciferase driven by the     interferon stimulated response element promoter (pISRE-Luc) (Agilent     Technologies). Full-length human STING (Gene ID 340061) and     full-length human cyclic guanine adenine synthase (cGAS) (reference     sequence NM_138441.2) was cloned into mammalian cell expression     vectors containing a cytomegalovirus promoter. Transfections were     prepared using a cell suspension with Fugene® 6 following the     manufacturer's instructions (3:1 Fugene®:DNA). Fifty microliters of     the transfection suspension was dispensed into wells of a 384-well     plate containing 250 nL of a compound of Formula (I-N), (I-P) or     (I). The final well composition contained 20,000 cells/well, 1 ng     STING, 20 ng pISRE-Luc, and empty vector pcDNA3.1 (Invitrogen) to     bring the total DNA concentration to 125 ng. Control wells expected     to generate maximal activation of STING were cotransfected with a     cGAS expression plasmid. Plates were sealed and incubated for 24     hours at 37° C. The expression of firefly luciferase was processed     using Steady-Glo® luciferase assay system (Promega) and was analyzed     using a standard laboratory luminescence plate reader. Data was     normalized to luminescence response in the presence of cGAS, was     plotted as a function of compound concentration, and fit using a     standard model of receptor activation to derive the pEC₅₀.     -   Using the functional assay III (HEK WT agonist assay) described         above, Examples 1-23, 25-42, 44, 47-55, 57-61, 63-94, and 97-197         exhibited pEC₅₀ values in the range of 4.4 to beyond the upper         limit of the assay at 9.1. Examples 1, 3, 8, 100, 116, and 194         exhibited pEC₅₀ lower than 4.3. For example, pEC₅₀ of for         following examples are:
